Use the search tool on the NPIdb website to search for an NPI number by the name of the provider or organization. The database provides results that include information such as a provider's location, credentials and specialty, and results are limited to 50 records. The NPI database is regularly updated, though some providers fail to change their information when they move or change their practice, which may result in outdated information, notes NPIdb.org. The search tool returns name results based on variant spellings.

This legislation requires providers and health plans to use NPI numbers for all billing and administrative purposes, and disallows the continued use of previous identification numbers. Health care providers and organizations already assigned identification numbers by Medicare associate those numbers with NPI numbers in the system Medicare uses to process claims.Learn more about Health Insurance
